This report studies a number of quantum cloning machines, motivated by their relevance to the field of quantum cryptography. Following a review of basic notions, the report looks at the Buzek-Hillery cloning machine and its generalizations using an approach due to Werner. With this background, an attack on the BB84 protocol by a particular type of cloning machine is considered and a security criterion for the protocol under such an attack is derived.
